2004 Ford F150 5.4L

[jwingate85]

I have a 2004 Ford F150 5.4L 2wd I use to tow and haul. The old girl is getting a little sluggish from a stop with 176k miles on her. I have a Diablosport i2 I use on my 2011 Mustang.

I have been contemplating if I should buy a new license for the F150 and see if the Diablosport tune would be at any benefits to her. Thoughts? Is there any data on the F150 5.4L Diablosport tunes?

they wake up nicely, we had an 04 5.4 for years that we used for the tune development.
I remember the first time I got in and drove it stock, I thought it was broken

Could you dig up any data on that? What the gains were.

Thanks,

Honestly cant believe I found this.....

Our 04 F150 stock vs 93 perf tune.
Stock run was made with speed limiter in place so its tough to see, but the gains are there.
